Contraindications |
|
Hypersensitivity to becaplermin or any component of its formulation; known
neoplasm(s) at the site(s) of application; active infection at ulcer
site |
|
|
Warnings/Precautions |
|
Concurrent use of corticosteroids, cancer chemotherapy, or other
immunosuppressive agents; ulcer wounds related to arterial or venous
insufficiency. Thermal, electrical, or radiation burns at wound site. Malignancy
(potential for tumor proliferation, although unproven; topical absorption is
minimal). Should not be used in wounds that close by primary intention. For
external use only. |

|
Adverse
Reactions |
|
<1%: Erythema with purulent discharge, ulcer infection, tunneling of
ulcer, exuberant granulation tissue, local pain, skin
ulceration |
|
|
Stability |
|
Refrigerate at 2°C to 8°C
(36°F to 46°F); do not
freeze |
|
|
Mechanism of
Action |
|
Recombinant B-isoform homodimer of human platelet-derived growth factor
(rPDGF-BB) which enhances formation of new granulation tissue, induces
fibroblast proliferation, and differentiation to promote wound
healing |
|
|
Pharmacodynamics/Kinetics |
|
Onset: Complete healing of diabetic ulcers in 15% of patients within 8 weeks
and 25% of patients at 10 weeks
Absorption: Systemic absorption is minimal
Distribution: Binds to PGDF-beta receptors in normal skin and granulation
tissue |
|
|
Usual Dosage |
|
Adults: Topical:
The amount of becaplermin to be applied will vary depending on the size of
the ulcer area. To calculate the length of gel applied to the ulcer, measure the
greatest length of the ulcer by the greatest width of the ulcer in inches. Tube
size will determine the formula used in the calculation. For a 15 or 7.5 g tube,
multiply length x width x 0.6. For a 2 g tube, multiply length x width x 1.3.
Note: If the ulcer does not decrease in size by ~30% after 10 weeks
of treatment or complete healing has not occurred in 20 weeks, continued
treatment with becaplermin gel should be reassessed. |

Patient
Information |
|
Hands should be washed thoroughly before applying. The tip of the tube should
not come into contact with the ulcer or any other surface; the tube should be
recapped tightly after each use. A cotton swab, tongue depressor, or other
application aid should be used to apply gel.
Step-by-step instructions for application:
Squeeze the calculated length of gel on to a clean, firm, nonabsorbable
surface (wax paper)
With a clean cotton swab, tongue depressor, or similar application aid,
spread the measured gel over the ulcer area to obtain an even layer
Cover with a saline-moistened gauze dressing. After ~12 hours, the ulcer
should be gently rinsed with saline or water to remove residual gel and covered
with a saline-moistened gauze dressing ( without gel).
